The level of different types of fuel production in the UK over a 20-year period was delineated through the line graph.
As can be seen from the chart, the UK consistently produced the amount of petroleum much more than the other fuel types during the depicted timescale. While petroleum and coal witnessed fluctuation,natural gas yield experienced a negligible increase.
Among the three kinds of fuel, the production level of petroleum constantly led the way. Its statistics started at roughly 100 million tonnes and rose to about 130 tonnes in the two ensuing years then stayed unchanged until 1987 before dropping back to the initial level in around 1988. After a trivial fall, the amount of petroleum generated in the UK rebounded to its peak, about over 130 tonnes in 1966 regardless a marginal decline to approximately 120 tonnes by the conclusion of the timescale.
Coal, in 1981, made up for 80 million tonnes of oil, which doubled the output of natural gas,before having went down considerably to nearly 50 tonnes in 1985, then experienced a recovery to nearly 70 tonnes only after 2 following years. Despite fluctuations in the initial six years from 1981, the production level of coal decreased to slightly under 40 tonnes by the end of the period. Simultaneously, natural gas production kept its stability by about 40 million tonnes of oil from 1981 to 1994, and then ascended to exceed coal’s figure since 1987, reaching the second rank in 1000 with over 80 tonnes manufactured.
